Emergence of Calabi-Yau manifolds in high-precision black hole scattering Open
Using the worldline quantum field theory formalism, we compute the radiation-reacted impulse, scattering angle, radiated energy and recoil of a classical black hole (or neutron star) scattering event at fifth post-Minkowskian and sub-leadi…

Calabi-Yau periods for black hole scattering in classical general relativity Open
The high-precision description of black hole scattering in classical general relativity using the post-Minkowskian (PM) expansion requires the evaluation of single-scale Feynman integrals at increasing loop orders. Up to 4PM, the scatterin…

Conservative Black Hole Scattering at Fifth Post-Minkowskian and First Self-Force Order Open
We compute the fifth post-Minkowskian (5PM) order contributions to the scattering angle and impulse of classical black hole scattering in the conservative sector at first self-force order using the worldline quantum field theory formalism.…

Conservative Black Hole Scattering at Fifth Post-Minkowskian and First Self-Force Order Open
We compute the 5PM order contributions to the scattering angle and impulse of classical black hole scattering in the conservative sector at first self-force order (1SF) using the worldline quantum field theory formalism. This challenging f…

Tidal effects and renormalization at fourth post-Minkowskian order Open
We determine the adiabatic tidal contributions to the radiation reacted momentum impulse Δpiμ and scattering angle θ between two scattered massive bodies (neutron stars) at next-to-next-to-leading post-Minkowskian order. The state-of-the-a…

Two-photon microscopy using fiber-based nanosecond excitation Open
Two-photon excitation fluorescence (TPEF) microscopy is a powerful technique for sensitive tissue imaging at depths of up to 1000 micrometers. However, due to the shallow penetration, for in vivo imaging of internal organs in patients beam…
